To all whom it may concern:

Be it known that I, WILLIAM T. DULANY, .T r., a citizen of the United States, residing at New York city, in the county of New York,

-State of NewYork, have'invented certain new and useful Improvements in Electric-Railway-System Conduite, of which the following is a specification, reference being had therein to the accompanying drawings;

The objects of myimprovements are to provide in connection with two conductors or trolley wires placed within a conduit and insulated therefrom, a trolleystandard containing within the wearing plates, Hat metal plate conductors made in series with fuse blocks or cut outs above and also under the points of contact of the standard with the slot of the conduit, so that if the wearing plate on one side of the standard becomes cut or worn through while a-car carrying the standard makes one of `its trips, the plate conductors on the opposite side will continue to transmit power to the motor of said car.

Another object is to provide a cross fuse connection between the conductors of the standard to connect them so that if the wearing plate on either side of the standard becomes worn through or short circuited that the said cross fuse connection becomes operative and supplies the necessary current to operate the car motors by crossing the cur- I rent from right to left in the conductor plates and vice versa. Another object in making the crossffuse connection between the conductor plates is to.

supply four paths for the current to travel,

in case of accidents to the standard before reaching switches for the car, namely, up both sides ofstandard iffno fuses are burnedout, up standard from right to left through cross fuse g2 if the section fuse g on leftside below the wearing plate and the corresponding upper fuse h on the right side ofthe head block P of the standard are burned and vice versa.

Another object is to divide the conduit sys tem into sections; said sections being connected to their respective feeder conductors, and said feeders are connected at theirswitch board terminals in such manner as to form a metallic circuit.

one of the trolley arms mounted thereon.

Fig. 2 is a side view of the lower portion of thetrolley standard broken away at the top vto show the position of the four conductor plates and their insulators. Fig. 3 is a top View of the standard showing themeans for connecting the conductor plates e with their respective fuses h, and fuse terminals 'h3 and from the latter through the wires h2 to the motor, and also ythe wires h4 through which the fuse terminals are connected together. Fig. 4 is a top view of the front (or rear) bar of the standard with portions of the side plates and insulatedconductors. Fig. 5 is a front view of the lower portion of the series of plates constituting the conductors with the fuse blocks connecting the upper conductors c with the bottom conductors e2. Fig. 6 is a transverse vertical section of the plate conductors ev e and c2 with their connecting fuse blocks for crossing the electric current from the lower to the upper plate conductors if one of the fuses in the standard'is burned out. Fig. 7 isfa perspective view of the head block of the standard showing tongueslp1 pendent therefrom on the front and rear of the standard, to protect it on the level of the slot ofthe track conduit. Fig. Sis a transverse vertical section ofthe plate conductors nearly similar to that shown in Fig. 6 but showing all the plate conductors and their fuse blocks. Fig. 9 is a transverse vertical section of the ytrack and conduit showing the two trolley wire conductors within sai'd conduit and the feeder cables of the conductors. Figs. 10 and l1 are transverse vertical sections on a larger scale of portions of the conduit with the conductor supporting bracket attached thereto. Fig. 12 is a side view of the conductor clamp and insulator shown in Fig. 10 with feederconductor N2 attached thereto. Fig. 13 is a top view of the bracket shown in Figli.

In said drawings A represents the trolley standard, and B the trolley journal bearings that are projecting from the sides of the stand- IOO ard adjacent to the bottom thereof and are secured thereto by means of flan ged cap-plates ci. The standard consists of side plates 7c that are bolted to the front and rear bars K, each of said bars being provided with a tongue as shown in Fig. 4, that extends some distance between the plates 7c and to which the latter are bolted, the space between the tongues of the bars K and the side plates 7e constituting a rectangular conduit for the reception of the fiat metal conductors e e2 and their mica insulators ff2f3. The central insulator fseparates the conductors c and e2, the insulators f2 protect them from contact with the side plates 7c, and the insulators f3 protect them from contact with the tongues of the bars K and the inner edges of the conductors e from each other.

The inner end of each trolley journal B is provided with a anged head to permit it to be secured to the plate conductors c2, by means of the cap plates a; but upon each journal B, and around the flange of its head is placed a sleeve b of insulating material that protects it from contact with the side plates 7c and with the cap plates ct.

Each conductor consists of three pieces, viz: the bottom plate conductor ee and the two upper plate conductors c that are united to the conductor e2 by means of fuses g and g2 of any suitable construction, but preferably as shown in Figs. G and 8 of short plates having their ends grooved to receive the ends of the conductors.

The location of the fuses g and g2 is shown to be at a short distance from the trolley j ournals B. They may be at a higher point, but said point must be below the location of the wearing plates k2, and beneath the shield J. Said plates 7a2 of the standard are located thereon, when in use, on the level of the edges of the slot of the underground conduit.

The upper end of the standard is received in a metal head block P said block having pendent therefrom a rectangular sleeve p through which boltsp2 are made to pass horizontally to engage with the bars K of the standard and fasten the trolley standard to head block P. The head of the block P has rboltsp3 passing vertically therethrough to seeure it to the frame of the car trucks. The head block of the standard is also provided with fuses (eut outs) h, the electric current passing thence through conductors h2 to the motor, dce., of the car. The head block is also provided with tongues p4 secured in vertical grooves therein and pendent therefrom on the front and rear to protect the front and rear bars K, ou the level of the slot of the track-conduit.

To prevent mud and water that may be descending upon the standard, from reaching the fuses g and g2 or the trolleyjournals and and their arms, and producing short circuit, shield J is bolted to the side plates le of said standard, a short distance above said trolleyr journals and fuses g g2. Said shield consists of arches formed of angle bars bent suitably with their outer flange turned up nearly parallel with the standard, and the lower portions ot said arches extend a suitable distance in front and rear ofthe standard.

The trolley arms d are pivotally mounted upon the outer end of each journal B and and are retained thereon by means of a washer n and nut n2. Each trolley arm d is provided with two grooved rollers d2 connected in tandem to better facilitate their passage over the ends of each independent section conduc tor in the underground conduit without interrupting the electric current. To keep the rollers d2 normally pressed upon the conductor wire a spring C is coiled upon the end of each journal B, and has one end secured to said journal, while the opposite end ot' said spring bears upon the inner end of each, arm et.

The trolley conduit D has angle iron plates D2 on top thereof at a suitable distance apart to provide between them the slot for the passage ot the standard A. Each angle plate D2 has brace bolts D3 laterally extended therefrom that connects it with the rails e of the track. To the yoke plates M of the conduit are attached brackets m and m', the inner ends of which project within the conduit and support insulators m2 and m3, and the latter carry clamps m4 for the trolley conductors N. Upon said brackets are also placed the distributing feeder conductors N2 that carry the electric current from the power station to each section of the trolley conductors of the under ground system. The conduit D is provided at suitable distances apart with drainage pipes d4 that are connected with sewers Having now fully described my invention, I elaim f 1.
